CRUDE-OIL BURNER.

Specification of Letters Patent.

Patented June 14, 1921.

Application filed September 25, 1919. Serial No. 326,143.

To all whom it may concern:

Be it known that I, WATSON /V. HoLMns, a citizen of the United States of America, residing at Austin, in the county of Travis and State of Texas, have invented new and useful Improvements in Crude-Oil Burners, of which the following is a specification.

The object of the invention is to provide an efiicient burner for crude or fuel oil of the heavier types wherein a relatively high degree of heat is required in order to produce vaporization, and in this connection to provide a burner which is suitable for use in connection with domestic cooking and heating stoves and which therefore may be used in connection with a fuel which is of less explosive and therefore less dangerous quality than the more volatile ils now in common use for this purpose. f

To this end the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanyingdrawing, it being understood that changes in form and proportion may be resorted to within the scope of the claims without departing from the principles involved.

In the drawings:

Figure l is a sectional view of the burner arranged in the operative position in the fire box of a stove.

Fig. 2 is a plan view of the burner.

Fig. 3 is a detail view of the burner cap and draft conductor.

Essentially the device consists of a burner plate 10 provided with an annular rirn or wheel 11 to provide an ignition pan for the reception of the fuel oil, a burner cap 12 which is of arched construction and spans and incloses the ignition pan, being provided with burner openings or slots 13 in its side wall close to the plane of the burner plate and a down draft conductor 14 which communicates with the burner cap at its center and is preferably enlarged or expanded toward its upper or inlet end which may be provided as shown in the drawing with a flange 1.5 to rest upon the surface of the stove top 16, said conductor passing through a suitable opening provided in the stove top.

The fuel feed pipe 17 extends upward through a central opening in the bottom of the ignition pan and is provided with a fuel outlet nozzle or jet 18, of reduced diameter which is disposed axially in the burner cap and preferably extends a short distance upward into the lower end of the down draft conductor as indicated in the drawing. Obviously the feed pipe should be provided with a suitable controllingvalve indicated at 19 wh1ch may be located at any convenient point, and after a sufficient quantity of fuel has been deposited in the ignition pan and has been ignited the heat of the flame, being communicated to the'adjacent parts of the burner will produce vaporization after whlch the controlling valve may be opened to feed the fuel at the desired rapidity to suit the purpose for which the burner is being used. The ignition takes place at the burner openings or slots 13 surrounding the ignition pan and the air necessary to supply the same is induced downwardly through the conductor 13 and passes around the fuel nozzle or jet, and if desired the burner plate may be extended as indicated in the drawings and provided with an upstandingwall 20 having suitable slots or openings 2] to form a basket which serves as a means for concentrating the flame and applying itefrfectively to the under surfaces of the stove plates. This concentration also serves to maintain the burner cap and plate and related parts at such a temperature as to insure the vaporization of the fuel at a sufficiently rapid rate to effectively supply the flame.

What is claimed is:

l. A burner having a burner plate and a fuel supply jet for depositing fuel thereon, an arched burner cap spanning the burner plate around the jet outlet and provided in its wall with burner openings, a down draft conductor communicating with the burner cap in an area surrounding said outlet, and a heat concentrating basket surrounding the burner cap and the adjacent portion of said conductor and having perforatml upstanding walls.

2. A burner having a burner plate and a fuel supply jet for depositing fuel thereon, a burner cap spanning the plate upon the jet outlet, draft conducting means communicating with the cap in the area of the jet outlet, and a heat concentrating basket surrounding the cap and having perforated upstanding walls.

in testimony whereof I my signature.
